Here is your short paragraph on Plants !
Science has proved that all plants are living organisms. Plants belong to the kingdom called Plantae. Plants include other organisms like bushes, vines, mosses, grasses, trees, green algae and herbs. Study of plants in science is known as botany.
Botany has identified around 3, 50,000 species (extant species) of plants such as bryophytes, seed plants, fern allies & ferns. Viridiplantae (green plants) prepare their own food in the presence of sunlight through the process called photosynthesis.
Plants are directly or indirectly connected with our life on earth. Plants benefit us in a number of ways. Plants provide seeds such as wheat, rice, corn etc that we eat in our daily life. Plants also provide us tasty fruits that gives us minerals & vitamins. Apart from food plants also provide us oxygen, shelter, fruits, food, timber, wood, fuel and medicine.
Plants also keep a check over pollution, soil erosion and floods and protect us. Plants help us against landslides and stops spreading of deserts.
Plants release oxygen which is very essential for our survival. Less number of plants on earth would increase the level of carbon dioxide in the environment. Increase in carbon dioxide is very harmful for the survival of human beings and animals on earth. Plants need good cultivating soil and water to grow.
The type of soil & water directly affects the growth of a plant. It should be noted that plants need to be nurtured by water in the absence of chemicals. Many people all around the world are using chemicals thinking that plants would grow healthier with the help of oxygen. But this perception is totally wrong. Instead chemicals alter the tastes of fruits and vegetables & are very harmful for human beings.
Plants play a vital role in preserving the fauns & maintaining ecological balance. Today countless plants are destroyed by mankind for various reasons at an alarming rate. It is seen that human beings are unable to realize the importance of plants in their lives.
Thousands of plants are being cut down to make furniture and paper. It is very important for all of us to grow more trees and plants and protect the existing ones. Forestry should cover a larger area & trees should be grown over spare cultivated land.
Plants add quality to our living. Without plants human life would become miserable because we all are dependent upon them. It is very difficult to imagine life without plants. Absence of plants will lead to desolation & deserts all around us.
